Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

The PSC motor uses a capacitor and has good running efficiency. When a PSC motor is used in compressors, it makes use of two capacitors attached to its wiring. The first one serves as a start ...

The Turbolytic50 is a replacement motor-start capacitor-with microfarad ratings from 21 to 324 mfd at 330vac. According the manufacturer, it can replace any one of 50 popular motor start capacitors ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

Efficiency standards were once confined to integral horsepower motors but may soon apply to small motors and make certain kinds impractical to manufacture. Today, the electric motors that are of most ...
